This article contrasts the normal method for drawing Lewis structures with a two-step systematic approach. The latter approach uses a known molecular connectivity and a knowledge of the number of valence electrons that each atom possesses to visualize bonds that are formed by pairing electrons, one from each atom. This process is repeated until at…

While computer simulations are a key element in understanding and doing science today, their nature and implications for science education have not been adequately explored in the relevant literature. In this article, (1) we provide an analysis of the methodology and epistemology of computer simulations, aiming to contribute to a sound and…

Human anatomical specimen museums are commonly used by medical, nursing, and paramedical students. Through dissection and prosection, the specimens housed in these museums allow students to appreciate the complex relationships of organs and structures in more detail than textbooks could provide. However, it may be difficult for students,…

Item analysis is an integral part of operational test development and is typically conducted within two popular statistical frameworks: classical test theory (CTT) and item response theory (IRT). In this digital ITEMS module, Hanwook Yoo and Ronald K. Hambleton provide an accessible overview of operational item analysis approaches within these…

Physiology is commonly taught through direct experience and observation of scientific phenomena in "hands-on" practical laboratory classes. The value of such classes is limited by students' lack of understanding of the underlying theoretical concepts and their lack of confidence with the experimental techniques. In our experience,…

Purpose: Previous results show that the anesthetists' activity during the planning phase is aimed at neither identifying risks nor pinpointing the adverse events likely to occur; rather, it is to devise "manageable situations" that are adapted to their own competences. The present paper focuses on the issue of understanding how, in…

We live in a society where Technology has an important position in our diary activities. Everybody wants to have the last device to be in contact with his family and friends. Additionally, these took are being applied in other fields such as Education. One of these tools is: Virtual reality that can respond the need of our students. It allows the…

Virtual reality (VR) as computer-mediated 3-D environments including real-life situations presented via different tools in which users can interact effectively with visuals. This study is significant as it primarily aimed to investigate effects of VR on retention by comparing it with traditional 2-D videos. The main aim of this study is to compare…

Although research on entrepreneurial attitude and intention has received so much attention from scholars, only few studies have investigated the effect of value, usefulness, and pleasure associated with business simulation games, and how these values affect students' attitude and intention toward entrepreneurial activities. In this study,…

Virtual classroom simulations can offer pre-service teachers unlimited opportunities for teaching practice that help them sensitize to classroom diversity. The purpose of this case study was to describe a collaborative simulation design studio initiated between two universities in South Korea and U.S.A. while American pre-service teachers visited…

Categorical perception (CP) effects manifest as faster or more accurate discrimination between objects that come from different categories compared with objects that come from the same category, controlling for the physical differences between the objects. The most popular explanations of CP effects have relied on perceptual warping causing…

This study presents a quantitative analysis of pre-emptive strategies used by first language speakers in talk addressed to second language speakers with moderate proficiency. The strategies identified in the conversations are reformulation, simplification, left-dislocation, and decomposition. The data come from simulated emergency calls in which…

In field placements, preservice music teachers (PMTs) rarely have the opportunity to communicate one-to-one with parents/caregivers. Situated within a clinical environment, this study examines how PMTs engage with a concerned mother whose daughter did not have a successful audition for a school musical. We approach this inquiry from a unique…

Recent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes:…

Evidence-based remediation options are limited for nursing students who fail their clinical competency evaluations. Scholarly literature provides a paucity of studies related to the use of simulation-based technology to remediate nursing students. The research question focused on the difference in the initial competency demonstration evaluation…
